AI Technical Summary
Traditional tube expansion equipment has poor versatility when processing stainless steel lined composite steel pipes, requiring frequent mold changes or parameter adjustments, and it is difficult to accurately control the expansion force, resulting in low production efficiency and damage to the inner wall of the steel pipe.
A tube expansion device for stainless steel lined composite steel pipes was designed. It adopts a telescopic component and clamp structure. The telescopic rod and clamp are automatically clamped and positioned by motor drive. Combined with the rotational connection between the lower disc and the cylinder, uniform control of the tube expansion force and automated operation are achieved.
This process ensures uniform and precise force application during tube expansion, avoids damage to the inner wall of the steel pipe, improves the fit and production quality of the composite steel pipe, reduces labor intensity, and enhances the stability and consistency of tube expansion quality.
